RMP400 basics
Introduction
The RMP400 offers an unrivalled combination of size, accuracy, reliability and robustness, and allows
high-accuracy probing on small to medium machining centres or other machines where line-of-sight
problems affect optical signal transmission.
Successfully combining patented RENGAGE™ strain gauge technology with the patented frequency
hopping radio transmission system of the RMP40, the RMP400 provides existing probe users with a
simple upgrade to solid-state strain gauge technology and all the associated benefits this brings:
•
excellent 3D performance to allow probing of contoured surfaces;
•
improved repeatability in all probing directions;
•
a low triggering force combined with low pre-travel variation to provide high accuracy, even when
used with long styli;
•
a proven ten-fold improvement in life (10 million triggers);
•
the elimination of reseat failures;
•
high resistance to machine tool vibration;
•
resistance to shock and false triggering through the use of solid state accelerometers.
In addition to providing high-accuracy measurement on your machine tool, the RMP400 also offers:
•
Faster calibration:
On complex 3D parts, it is common to measure in several different directions. Each direction
of a standard mechanical probe must be calibrated, to ensure that the pre-travel variation is
compensated in the measurement.
Performing this calibration for every 3D direction can be time-consuming.
The RMP400 has almost no pre-travel variation, so a single calibration value may be used for any
probing angle in 2D or 3D. This results in a vastly reduced calibration time. An additional benefit is a
corresponding reduction in errors introduced by environmental changes within the machine during
a long calibration cycle.
•
The ability to be used in applications where axial and radial reorientations are used, enabled by the
use of solid state accelerometers:
The auto-reset function is required and recommendations should be followed for optimum
metrology performance.
